#17answer parts a-d please

(6%) Problem 17: A bank of batteries, total emf & = 4.5 V, is connected with resistor R = 180 kS, capacitor C = 680 pF, and two-pole switch S as shown. The switch is initially set to point b so that the resistor and capacitor are in series. The switch is left in this position for a sufficiently long time so that the R capacitor is completely discharged.
